Sodium Pca ●
TL;DR. This ingredient is a water-binding humectant used to increase skin and hair hydration. It also helps improve slip and reduce the dry feel that can come from surfactants or alcohol-heavy formulas.
What does Sodium Pca do in a cosmetic formula?
This ingredient is a water-binding humectant used to increase skin and hair hydration. It also helps improve slip and reduce the dry feel that can come from surfactants or alcohol-heavy formulas.
Is Sodium Pca clean?
From a clean-beauty perspective, it is well-tolerated, not a common allergen, and has little restricted-list friction. Sensitivity is uncommon, though very high levels can feel tacky or contribute to mild stinging on compromised skin.
Is Sodium Pca sustainable?
This material is typically made from amino-acid or fermentation-derived feedstocks, with some variation by supplier. It is water-soluble and readily biodegradable, so it has a favorable environmental profile compared with persistent film-formers or silicones.
Is Sodium Pca COSMOS-approved?
It is generally permitted in COSMOS natural and organic formulas when produced from approved natural-origin feedstocks and allowed processing steps. It fits Green Chemistry principles well because it can be bio-based, biodegradable, effective at low levels, and does not require heavy solvent systems in use.
How does Sodium Pca work chemically?
The molecule is an ionic, highly water-soluble lactam carboxylate that holds water through strong hydrogen bonding and osmotic effects. Typical use levels are about 0.2% to 5%, and it is usually formulated in the water phase with broad pH compatibility, though high doses can add tack and electrolyte load.
